Description

  In order to facilitate the removal of the contents and the storage of the remaining contents after opening the bag filled with various contents such as pet food, foodstuffs, and medicines, the present invention The present invention relates to an opening / closing device temporarily attached to an opening.

Granules, powders, and the like of pet food and food are often stored in bags and sold. In recent years, from the viewpoint of environmental protection and cost reduction, refills such as medicines are often sold in bags instead of hard containers.
However, the contents filled in the bag body have a drawback that it is difficult to take out, and when the contents remain, in order to store it in the bag body, the opening of the bag body is tied with a rubber band or the like. It is necessary, but opening and closing is very troublesome.
Therefore, the following proposal has been made as an opening / closing device temporarily attached to the opening of the bag body. That is, the opening peripheral edge of the bag body is inserted into the inner hole of the first cylindrical body having the external thread formed on the outer peripheral surface, and the opening peripheral edge of the bag body protruding from the inner hole is used as the first cylindrical body. Folded to the outer peripheral surface on which the male screw is formed, the second cylinder is externally fitted to the folded portion, and the female screw formed on the inner peripheral surface of the second cylinder is the first cylindrical body By screwing onto the male screw, the opening periphery of the bag body is sandwiched between these screws, and an opening is formed that is retained by the first cylinder and the second cylinder relative to the bag body. The Further, there is an opening that can be opened and closed by a lid member that is screwed into a male screw provided on the outer peripheral surface of the second cylindrical body (see Patent Document 1).

Moreover, in the structure substantially the same as the above, the opening peripheral edge of the bag body is covered from the outside of the first cylinder body, and the female screw of the second cylinder pair is screwed to the male screw of the first cylinder body. Thus, the opening periphery of the bag body is sandwiched between these screws, the first cylindrical body and the second cylindrical body form an opening retained with respect to the bag body, and the opening is further In addition, there is one that can be opened and closed by a lid member fitted to the second cylindrical body (see Patent Document 2).
Japanese Utility Model Publication No. 61-178340 Special table 2002-503600 gazette

When the above-mentioned conventional apparatus is attached to the opening of the opened bag, the contents can be taken out and stored only by opening and closing the lid member. However, in any of the conventional techniques, the opening portion (opening end portion of the second cylinder body) formed of the first cylinder body and the second cylinder body and retained in the bag body is an opening / closing device. In other words, it has a simple cylindrical shape, and the lid member is merely a flat bottomed cylindrical shape that simply opens and closes the opening.
Thus, in order to take out the contents of the bag body, the bag body is generally lifted and shaken so that the opening portion faces downward. In this case, if the opening is a simple cylindrical shape as in the prior art, if the contents of the bag is a relatively large granular or rectangular solid, the contents concentrate on the opening, Combined with their own weight, they stayed in the vicinity of the opening, and there was a problem that they could not be taken out well just by shaking. On the other hand, when the content is a powdery material, there are problems such as splashing in all directions from the opening at the time of taking out, and in the case of a fluid material, there are problems such as side leakage.

  Therefore, the present invention has been made in view of the above circumstances. First, regardless of the contents of the bag body, the contents stay in the vicinity of the opening, or are scattered or laterally leaked from the opening. An object of the present invention is to provide a temporary opening opening / closing device for a bag body that is difficult to wear. Moreover, in order to achieve such an object, another object is to add new convenience.

In order to achieve the object, the present invention takes the following technical means.
(1) That is, the temporary opening / closing device according to the present invention includes an insertion portion that is inserted into the bag body from an opening formed in the bag body, and a male screw that protrudes outward from the opening of the bag body. A first cylinder having a portion;
A female screw part screwed into the male screw part of the first cylindrical body is provided, and the peripheral part of the opening formed in the bag body is sandwiched between the first cylindrical body and the first cylindrical body. An opening forming body is constituted by a second cylinder that is fixed to the opening of the bag and that forms an opening that is retained with respect to the bag together with the first cylinder,
A temporary opening / closing device for a bag body, which is detachably attached to the opening forming body and is provided with a lid member that opens and closes the opening of the opening forming body,
The opening forming body is provided with a spout piece protruding outward from the bag body, and the spout piece seems to be cut in a direction oblique to the axial direction of the opening forming body. The lid member is configured as a container having a depth that can accommodate the entire spout piece and the tip thereof.

In this way, the spout piece protruding outward from the bag body has a shape that is cut in a direction oblique to the axial direction of the opening forming body. In any case, the contents can be easily removed without stagnation and clogging in the vicinity of the opening, or scattering or side leakage from the opening. Moreover, since the lid member is configured as a container having a depth that can accommodate the entire tip including the tip of the spout piece, it not only serves as a lid member but also protects the tip of the spout piece. It can also serve as a container from which the contents are taken out.
(2) In addition to the above, the opening forming body is provided with a scooping piece projecting inward of the bag body, and the scooping piece is oblique to the axial direction of the opening forming body. It can be set as the shape cut | disconnected in the direction to do.

  In this way, if the opening forming body has a shape in which the scooping piece protruding inward of the bag body is cut in a direction oblique to the axial direction of the opening forming body, If you make a small cut when opening the body, you can insert the tip of the scooping piece into that part and gradually insert the insertion part including the flange part of the opening forming body, so open the bag body opening too much Further, there is no failure that the opening forming body cannot be attached to the bag body or the sealing performance of the bag body is hindered. Moreover, even when the bag is fully filled with the contents, the insertion portion of the opening forming body can be easily inserted into the bag.

Furthermore, since the scooping piece can be guided toward the spout piece without causing the contents to stay inside the bag body, the content can be more suitably combined with the spout piece. It can be taken out.
(3) Further, the spout piece and the scooping piece provided in the opening forming body are cut in a direction oblique to the axial direction of the opening forming body so that the tip ends thereof coincide with each other. Each of such shapes is preferably in a substantially mirror-like symmetrical state with respect to a direction orthogonal to the axial direction of the opening forming body.

In this way, when the tip ends of the spout piece and the scooping piece are matched, the contents of the bag body pass through the scooping piece and the spout piece to the lid member which is the container of the take-out destination. You can take it out smoothly.
(4) Further, when at least one of the spout piece and the scooping piece provided in the opening forming body has a virtual tangent in a direction oblique to the axial direction of the opening forming body, On the other hand, it is preferable to have a bent portion lacking in an arc shape.
In this way, if the spout piece or the scooping piece is provided with a constricted portion, a wider open opening can be made to the outside and inside of the bag, so that the contents of the bag can be taken out and collected. Is more suitable.
(5) However, the degree of twisting of each of the spout piece and the scooping piece provided in the opening forming body is such that the scooping part of the spout piece is curled. The relationship is preferably smaller than the part. This is mainly because the scooping piece is easy to insert into the opening from the bag body and the function of collecting the contents of the bag body more widely, whereas the spout piece is taken out. This is because it is important to pour the contents so as not to spill into the lid member which is the receiving container from which the contents are taken out.

  When the temporary opening / closing device according to the present invention is attached to the opening of the opened bag body, the contents can be taken out and stored only by opening and closing the lid member, and the contents of the bag body can be checked. Therefore, the contents can be easily taken out without staying in the vicinity of the opening and becoming clogged, or without being scattered or leaking from the opening. Moreover, the lid member not only protects the tip of the spout piece, but can also serve as a container from which the contents are taken out.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 thru | or FIG. 8 has shown one Embodiment of the temporary opening part opening / closing apparatus 1 of the bag body which concerns on this invention. As shown in FIGS. 1 and 2, the temporary opening / closing device 1 for a bag according to the present embodiment mainly includes an opening forming body 4 including a first cylindrical body 2 and a second cylindrical body 3, and a lid member. 5 and is molded from a synthetic resin such as polypropylene or polyethylene, and preferably the whole is generally translucent or transparent.

As shown in FIG. 3, the first cylinder 2 has a cylindrical shape with an inner hole 6, and includes an insertion portion 8 including a flange portion 7 to be inserted into the bag A to be described later, and the bag A The external thread part 9 protruded outward is provided.
Further, a scooping piece 10 protruding inward of the bag body A is provided on the opposite side (downward in the drawing) of the male screw portion 9 with the flange portion 7 interposed therebetween. The scooping piece 10 has a shape that is cut in a direction that is oblique to the axial direction of the opening forming body 4, in other words, a shape that is the tip of a transplanted hand (scoop). Further, when the direction oblique to the axial direction of the opening forming body 4 is a virtual tangent line X, the scooping piece 10 and the bulging part 11 lacking in an arc shape with respect to the tangent line X and a bulge expanding in an arc shape. And a shape that draws an S-shaped curve in a side view.

On the other hand, the second cylinder 3 constituting the opening forming body 4 together with the first cylinder 2 has a cylindrical shape with an inner hole 13 as shown in FIGS. A female screw portion 14 to be screwed with the male screw portion 9 is provided. The second cylindrical body 3 is provided with a neck portion 16 adjacent to the female screw portion 14 (upward in FIG. 2) via a step portion 15. A pair of upper opening portions 17aL-shaped engaging grooves 17 opened upward are provided in the diameter direction of the second cylindrical body 3, and each engaging groove 17 has an engaging bulging portion 17b. .
Further, a spout piece 18 that protrudes outward from the bag A is provided adjacent to the neck 16 (further above in FIG. 2). The spout piece 18 has a shape that is cut in a direction that is oblique to the axial direction of the opening forming body 4, in other words, a shape that is the tip of a transplanted hand (scoop). . Further, the spout piece 18 has an arcuate portion 19 and an arcuate portion 19 that are not arcuate with respect to the tangent line X ′ when the direction oblique to the axial direction of the opening forming body 4 is a virtual tangent line X ′. It has a bulging portion 20 that swells in a shape that draws an S-shaped curve in a side view.

In addition, in this embodiment, the degree of curling (the degree of chipping) between the curled portion 19 of the spout piece 18 and the curled portion 11 of the scooping piece 10 is greater in the curled portion 19 of the spout piece 18. The relationship is smaller than that of the curled portion 11 of the scooping piece 10. On the other hand, the protruding length of the spout piece 18 is larger than the protruding length of the scooping piece 10.
And the said cover member 5 is comprised as a cup-shaped container with the depth which can accommodate the whole including the front-end | tip part 18a of the spout piece 18 of the said 2nd cylinder 3, as shown also in FIG. A handle portion 21 is provided on one side of the outer surface. Further, on the inner peripheral surface of the lid member 5, there are engaging protrusions 22 that engage with a pair of L-shaped engaging grooves 17 provided on the outer peripheral surface of the neck portion 16 of the second cylinder 3. A pair is provided so as to face the diameter direction of 5.

Further, the lid member 5 is engraved or printed with a graduation scale 23 that can measure the amount of the contents C of the bag A received by the lid member 5 so that the lid member 5 can be seen from the outer circumferential surface and / or the inner circumferential surface. Etc. are attached.
Thus, the temporary opening / closing device 1 according to the present embodiment is fixed to the opening of the bag A as follows.
First, a part of the bag A is cut in advance with scissors or the like, and an opening B is formed so that the tip of the scooping piece 10 of the first cylinder 2 can be inserted. Then, the insertion piece 8 such as the scooping piece 10 and the flange portion 7 of the first cylindrical body 2 is inserted into the bag body A from the opening B.

  At this time, since the scooping piece 10 has a shape that is cut in a direction oblique to the axial direction of the opening forming body 4, the opening B of the bag body A has a tip of the scooping piece 10. Even if the cut end is small enough to be inserted, the insertion portion 8 including the flange portion 7 of the opening forming body 4 can be inserted by gradually expanding the opening B from the tip of the scooping piece 10. Therefore, there is no failure that the opening B 4 cannot be attached to the bag body A and the sealing performance of the bag body A is hindered. Furthermore, even when the contents C are fully filled in the bag A, the insertion portion 8 including the flange portion 7 of the opening forming body 4 can be easily inserted into the bag A without being obstructed by the contents C. Can be inserted.

  Next, in a state where the male screw portion 9 of the first cylinder 2 protrudes outward from the opening B of the bag body A, the second cylinder 3 is externally fitted to the male screw portion 9, and the second cylinder 3 The female screw portion 14 of the first cylinder 2 is connected to the peripheral portion of the opening B formed in the bag A, and the female screw of the second cylinder 3 is connected to the flange portion 7 (or the male screw portion 9). The first cylindrical body 2 and the second cylindrical body 3 are connected by being sandwiched between the lower ends of the portions 14, and the opening forming body 4 is configured integrally. In addition, when the peripheral part of the opening B formed in the bag A is sandwiched between the male screw part 9 of the first cylinder 2 and the female screw part 14 of the second cylinder 3, the flange part 7 is not necessarily provided. Needless to say, in this case, however, it is needless to say that a backlash about the thickness of the bag A is required between the screw portions 9 and 14.

  And when the 1st cylinder 2 and the 2nd cylinder 3 are connected in this way and the opening part formation body 4 is comprised integrally, the inner hole 6 and the 2nd cylinder of the 1st cylinder 2 are comprised. The three inner holes 13 communicate with each other, and a shape-retained opening 24 is formed to communicate with the bag body A inside and outside. In addition, it is preferable that the inner hole 6 of the first cylinder 2 and the inner hole 13 of the second cylinder 3 are continuously communicated with each other on the inner peripheral surface without a step. Further, the spout piece 18 and the scooping piece 10 provided in the opening forming body 4 in this way are aligned with respect to the axial direction of the opening forming body 4 so that the directions of the respective front end portions 18a and 10a coincide with each other. The respective shapes that are cut in the oblique direction are set so as to have a substantially mirror-like symmetrical state with respect to the direction orthogonal to the axial direction of the opening forming body 4.

Next, in order to close the opening 24, each upper opening 17 a of the pair of L-shaped engagement grooves 17 provided in the neck 16 of the second cylinder 3 constituting the opening forming body 4, and a lid member The pair of engaging protrusions 22 provided on the inner peripheral surface of 5 are made to coincide with each other, and the lid member 5 is externally fitted to the neck portion 16 and rotated. Then, each engagement protrusion 22 gets over the engagement bulging portion 17b provided in each engagement groove 17 and is fitted with a click sound of “click”. Thereby, the opening part 24 which connects the inside and outside with respect to the bag body A is closed as shown in FIG.1 and FIG.10.
In addition, since the lid member 5 is configured as a container having a depth that can accommodate the entire spout piece 18 and the tip portion 18a thereof, the tip portion 18a of the spout piece 18 can be protected.

On the other hand, in order to open the opening 24, the lid member 5 may be rotated in the direction opposite to the above and removed from the opening forming body 4.
Then, in order to take out the contents C of the bag A, the bag A may be lifted so that the opening forming body 4 faces downward with the opening 24 opened as shown in FIG.
At this time, if the back surface 10b where the tip portion 10a of the scooping piece 10 of the first cylindrical body 2 exists is set in advance along the side D of the inner surface of the bag A, the weight of the contents C of the bag A Thus, the scooping piece 10 is supported so as to be pressed against one side D of the inner surface of the bag body A, and the opening forming body 4 is shaken with respect to the bag body A due to the “twist” of the bag body A. The spout piece 18 can be taken out or transferred to a container or the like as intended. This is effective particularly when the bag A is thin and vulnerable to bending force.

  Further, the scooping piece 10 is shaped so as to be cut in a direction oblique to the axial direction of the opening forming body 4, so that the contents inside the bag body A toward the spout piece 18 The material C can be guided without being retained. In addition, the scooping piece 10 has a tanged portion 11 and a bulging portion 12 that are not arcuate with respect to the tangent line X when the direction oblique to the axial direction of the opening forming body 4 is a virtual tangent line X. In addition, since the S-shaped curve is drawn in a side view, the bent portion 11 is wide open toward the inside of the bag body A, and the contents C of the bag body A are It is more preferable to stay in the opening portion, and it can be smoothly guided to the inner hole 6 of the first cylinder 2.

And the contents C which passed through the inner hole 6 of the 1st cylinder 2 reach the spout piece 18 through the inner hole 13 of the 2nd cylinder 3, and this spout piece 18 is also the opening part formation body 4. Since the shape is cut in a direction oblique to the axial direction, the content C stays in the vicinity of the opening 24 regardless of the type of the content C of the bag A. It can be easily taken out without clogging or scattering or side leakage from the opening 24.
Moreover, when the direction oblique to the axial direction of the opening forming body 4 is the virtual tangent line X ′, the spout part 18 and the bulging part 20 lacking in an arc shape with respect to the tangent line X ′. And has a shape that draws an S-shaped curve in a side view, so that the bulge portion 19 is wide open toward the outside of the bag body A, and the contents C of the bag body A Is taken out of the bag A without staying in the opening 24, and the bulging portion 20 suitably prevents the contents C from being scattered in all directions and leaking sideways, and the On the other hand, it can be sent out smoothly.

On the other hand, the lid member 5 has not only a role as a lid member but also a role as a container from which the contents are taken out. Therefore, the lid member 5 can be used as a temporary destination container, as in this embodiment. In addition, if the weighing scale 23 is provided, it is very convenient to take out the contents C while weighing the required amount. In particular, when the content C of the bag A is like pet food, it can be given while measuring the health of the pet and is very effective.
In addition, since the handle 21 is provided in the lid member 5, it is not only convenient for operation and carrying of the lid member 5, but also when the weight of the contents C is relatively small, the opening forming body In the state where the lid member 5 is attached to 4, the bag body A can also be used as a hand for carrying it.

By the way, in the said embodiment, the structure which closes the opening part 24 is provided in the inner peripheral surface of the L-shaped engagement groove | channel 17 provided in the neck part 16 of the 2nd cylinder 3, and the cover member 5. FIG. However, the structure is not limited to such a structure, but may be the same structure as the screwed structure of the first cylinder 2 and the second cylinder 3. Further, a forced fitting structure in which the inner peripheral surface of the lid member 5 is fitted on the neck 16 of the second cylindrical body 3 may be used.
However, in the case of a screwed structure in which a male screw portion is provided on the neck portion 16 of the second cylindrical body 3 and a female screw portion is provided on the inner peripheral surface of the lid member 5, a bag body is formed on the female screw portion of the lid member 5. It is conceivable that the residue etc. of the contents C of A will adhere and obstruct screwing, or may become unsanitary. However, as in the above embodiment, the lid member 5 side is like the engagement protrusion 22. Such a problem does not occur with the structure.

Although not shown, for example, a seal ring is fitted on the outer peripheral surface of the neck portion 16 of the second cylindrical body 3 so as to be in contact with the step portion 15, so that the opening forming body 4 and the lid member 5 are sealed. It is also possible to improve the sealing property and to improve the sealing property between the opening forming body 4 and the bag body A by adding a seal ring above the flange portion 7 of the first cylindrical body 2.
(Second embodiment)
FIG. 9 shows an opening forming body 4 made up of one cylindrical body 2 and a second cylindrical body 3 in the second embodiment of the temporary opening / closing device 1 for a bag according to the present invention.

The main difference between the second embodiment and the first embodiment is that, in the first embodiment, the spout piece 18 provided in the second cylinder 3 is the same as the first cylinder. The body 2 is integrally provided adjacent to the male screw portion 9 (upward in FIG. 9).
That is, a spout piece 18 that protrudes outward from the bag body A is integrally provided adjacent to the male screw portion 9 of the first cylinder 2 (upward in FIG. 9). In this case, the outer diameter of the spout piece 18 is slightly smaller than the outer diameter of the male screw portion 9.
Therefore, the spout piece 18 adjacent to the neck 16 (upward in the drawing) is not provided in the second cylinder 3 in the present embodiment. Since other configurations are basically the same as those of the first embodiment, the same reference numerals are given and detailed descriptions thereof are omitted.

  In addition, when the scooping piece 10 and the spout piece 18 are integrally provided in the first cylinder 2 as in the second embodiment, the neck portion 16 is not necessarily required on the second cylinder 3 side. An L-shaped engagement groove 17 that engages with the engagement protrusion 22 of the lid member 5 can be provided on the outer peripheral surface of the spout piece 18 of the first cylinder 2. In addition, the engagement between the lid member 5 and the opening forming body 4 is not the configuration of the engaging protrusion 22 and the L-shaped engaging groove 17, but, for example, the male threaded portion 9 of the first cylindrical body 2. Is provided in a wide range so as to protrude further upward than the female threaded portion 14 of the second cylindrical body, and a female threaded portion is formed on the inner periphery of the lid member in place of the engaging protrusion 22 of the lid member 5. In addition, the engagement between the lid member 5 and the opening forming body 4 may be a screwed structure between the female screw portion of the lid member 5 and the portion of the male screw portion 9 protruding further upward from the second cylinder 3. it can.
